    The withdrawal forces of a single fiber from parallel fiber bundles were measured with the torsion balance method. The experiments were carried out on four sliverlike bundles: crimped, regular, direct roller cutting viscose rayon, and cotton fiber.
    Each bundle was 1_??_2cm in length, and wrapped in cellophane tube having various diameters. Withdrawal force measured in this experiment corresponds to frictional force acting on a single fiber in a bundle which is streched by external force. The mean frictional withdrawal force of a single fiber from a bundle is affected by the fullness of the bundle (1-ε), mutual distance d (mm) of withdrawal fibers in cross-section of the bundle, and numbers of fibers N which are drawn together.
    The following results were obtained:
    (1) When a single fiber is drawn out of a bundle, the frictional force Fs (mg/cm) increases proportionally to the increase of the fullness of the bundle (1-ε). (Fig. 4.2)
    (2) When two strips of single fiber are drawn out together from the bunbles whose fullness remain constant, the withdrawal force is affected by the mutual cross-sectional distance d of withdrawal fibers; especially in the case of close contact of two fibers (d=0), value of Fs is equal to the withdrawal force of a single fiber from the same bundle, and as the distance of two withdrawal fibers are appart from each other in such a way that other fibers come between them, the value of Fs approaches twice that of a single fiber (Fig. 4.3).
    (3) The experiment shows that simultaneous withdrawal force Fs of many fibers increases linearly to the increase of withdrawal fibers number N, remainning (1-ε) and mutual distance (d>0) constant. (Fig. 4.4).
    The streching phenomena of fiber bundles, the effects of variation of (1-ε), d and N on the withdrawal force Fs of single fibre are the fundamental properties will be discussed in the paper to follow.

    The strength of the spun yarns which have lower twists is due to slip occuring between one fibre and the other rather than the breakage of the component fibre itself. The condition of the entanglement between one another of fibres may be altered by the kinds of fibres and their combinations. The relations between the various blend percentages of blended yarns of cotton and rayon staple fibres and the nature of the entanglement of their blended yarns are investigated.
    The results obtained are as follows:
    1) The yarns resist withdrawal of the 50% blended yarn has the minimum among the residual twists for the same load, therefore this yarn shows the good entanglement a the place of lower twists. The 50% blended yarn has the maximum nature of the entanglement in the range of lower twists which is the opposite result to the values of the spinning efficiency in the finished yarns, and it shows how the effects of the twists which are added to the blended yarns changes. The results above described in the range of lower twists may be due to the shape of the fibre and the coefficient of friction between the component fibres at the state of small lateral pressure followed from twists and so on.
    2) The untwist number which is necessary to give unit elongation decreases hyperbolically as the load added to the blended yarn increases, and especially it is shown that the blends which are rich in staple fibre are apt to elongate and withdraw.
    3) The nature of the entanglement changes by the untwist speed and in general the faster the untwist speed is, the greater the nature of the entanglement becomes.

    As it was stated in the previous report, the several properties of Vinylon were improved by adding boric acid to PVA spinning process. After the several experiments, it was found that the borated PVA spinning process could be easily applied to the industrial production.
    Typical spinning condition is as follows: Spinning solution PVA 14% (P=1400) contained 0.8% boric acid/PVA at 80°C Coagulation bath Saturated (NH4)2SO4 solution at 17_??_19°C pH value over 9.0 Bath length 1m. 1st Goddet 9_??_10m/min. 2nd Goddet 30m/min.
    Stretching bath Satulated (NH4)2SO4 solution over 90°C Bath length 2m. 3rd Goddet 60 m/min.
    The feature of the fibre thus obtained is hollow inside.

    In order to obtain some fundamental data on the interaction between disperse dyes and organic solvents, the solubilities of 1, 4-diaminoanthraquinone (DAA) in mixed solvents of carbon tetrachloride (CCl4) and ethyl alcohol were measured, and related functions of solubility are noted with the results as follows.
    1) An addition of C2H5OH into CCl4 increases the solubility of DAA remarkably, and it may be attributed to the existence of the difference in the affinity for DAA between CCl4 and C2H5OH. An application of mass action law shows that the affinity of C2H5OH is larger than that of CCl4 by about 2.3 kcal/mol.
    2) The solubilities in n-alcohol series indicate the existence at least of two forces-nonpolar force and polar force-
    3) The curve of ΔH0 versus ΔS0 is a straight line in a series of n-alcohol, and the point for CCl4 deviates from the line. Therefore, it may be suggested that the mutual correlation of nonpolar force and polar force in CCl4 differs from that in n-alcohol_??_

    On Blotch Method by machine printing specially among the printing methods using Vat dyestuffs, a few factors were measured in order to find the following: (1) Physical properties of printing pastes. (2) The influence of these properties on the result of printing, That is, on printing pastes for Blotch Method which uses all kinds of thickener, their viscosity, spinnability, sharpness, levelness and colour value, fixed value, fixed percentage etc. of the prints steamed in Flash Ager were measured.
    The results obtained are as follows:
    1) As printing pastes for Blotch Method, wheat starch, Sodium alginate and Schisa are suitable.
    2) Single thickener which excels from every point of view does not exist.
    3) As mixed printing pastes for Blotch method, mixture of Wheat starch and Sodium alginate are excellent.

    Relations between the density of the felt prepared from the carroted Angora rabbit furs and the carrotting factors, i.e. concentrations of the carrotting reagents (Hg(NO3)2, HNO3 and NaNO2), immersion conditions (temperature and time) and drying conditions (temperature and time) were studied. The experiments were designed by means of L27(313), and the data obtained were tested by means of the analysis of variance. As the result it was found that the concentration of NaNO2 is significant, while other factors are not significant at 5% level,

    The changes of physical properties mainly of viscose spun rayon and cotton fabrics with inner polymerization and condensation reactions of N-methylolacrylamide (MAM) and acrylamide (AM) were investigated. The results thus obtained are as follows.
    (1) Through the polymerization of AM within cotton fabrics both crease recoveries and strengths were not much improved, although some cross-linkings between polymer chains were recognized.
    (2) As for viscose spun rayon, crease recoveries, wash-fastnesses and shrinkage-proofing effects were excellent in MAM-treated fabrics and abrasion resistances excellent in AM-treated ones. These behaviors of MAM are similar to those of “reactant-type” resin and such serious faults of dimethylolurea-finished fabrics as lackings of wash-fastness and shrinkages by washes can be improved by its mixing with MAM.
    (3) After-treatments of MAM-treated fabrics with hexamethylenediamine or thereafter with HCHO give excellent crease-proofing effects as well as some strength elevations; cellulosic and mixed cellulosic fabrics treated by this method can be homogeneously dyed with acid dyes.
